Mexico’s Best Drilling Intercepts, Fourth Week of February 2026

Five companies published results from drilling campaigns in Mexico during the week leading to the PDAC convention.

Heliostar Metals announced assay results from the current drilling program at Ana Paula in Guerrero. The program’s goal is to convert inferred resources to higher confidence classifications and support the ongoing feasibility study (FS) as well to test the next set of exploration targets near the current deposit. The best result in this release was over 55 m long, averaging 9.71 gpt Au. This is a complex deposit with skarn, carbonate replacement and breccia affinities, with a late epithermal imprint.

Silverco Mining reported the final assay results from the 15,000 m 2025 drill program at Cusi, in Chihuahua. The program has extended by several hundred meters the San Miguel and San Juan veins mineralized sections. The Cusi project displays intermediate sulfidation epithermal style mineralization.

Capitan Silver reported assay results from nine holes from the reverse circulation (RC) drill program at its Cruz de Plata project in Durango. The company successfully encountered several high-grade intervals along the Jesús María trend, while final assays are pending for 25 holes. One diamond drill rig has arrived at the property and two more are expected to arrive in the coming weeks on this property with near-by intermediate and low sulfidation epithermal mineralization.

Minaurum Silver released results from its 50,000 m resource expansion drill program at its Alamos Silver project in Sonora. The current release includes drill intercepts from holes on the Europa and Quintera-Travesías zones. Six drill rigs are operating on the project at the time being. Alamos Silver displays intermediate sulfidation epithermal veins over imposed on earlier local carbonate replacement mineralization.  

Axo Copper presented results from ongoing drilling at its La Huerta project in Jalisco. The current drilling is testing the down-dip extension at Las Marias, “through a series of several planned holes ranging from approximately 350m to 450m in length”. Mineralization at La Huerta has been reported by Axo as of iron oxide-copper-gold (IOCG) characteristics.

Mexico’s Best Copper Drilling Intercepts in 2025

During 2025 sixteen companies presented copper results from drilling programs in twenty deposits located in nine states.

By a fair margin the best drill intercept was presented by Torex Gold at its Media Luna East deposit within its Morelos Complex in Guerrero. Although most of copper production in Mexico comes from porphyry copper deposits, in the period only two companies presented results from drilling campaigns in the distal epithermal parts of that type of systems.

Intermediate sulfidation deposits are the most numerous in the table below, particularly in the bottom half, with nine deposits comprised by La Colorada (Zacatecas), Alamos Silver (Sonora), Tahuehueto (Durango), Don David (Oaxaca), Los Gatos (Chihuahua), Plomosas-San Marcial (Sinaloa), El Tigre (Sonora), Pitarrilla (Durango) and La Reyna (Nayarit). Gran Pilar/El Pilar (Sonora) and Cristina are the intermediate sulfidation deposits linked to distal parts of porphyry copper systems.

Skarns systems display the second most common mineralization copper bearing intercepts, comprised by Media Luna East (Guerrero), ELG Underground (Guerrero), Bolivar (Chihuahua, El Limon Sur (Guerrero), and Media Luna West (Guerrero). Cerro Las Minitas (Durango) presents skarn and carbonate replacement deposits (CRD) mineralization, while Camino Rojo displays skarn, CRD and intermediate sulfidation epithermal mineralization.

La Huerta (Jalisco) is the only iron-oxide-copper-gold (IOCG) deposit in the table, and Campo Morado (Guerrero) the only representative of the volcanogenic massive sulfides (VMS) category.

Mexico’s Best Silver Drilling Intercepts in 2025

During 2025 thirty-four companies presented silver results from drilling programs in forty-five deposits located in eleven states.

GoGold Resources tops the table below with a 21.25 m interval averaging 2,077 gpt Ag from Los Ricos South in Jalisco, followed by Palmarejo, Pitarrilla, Plomosas-San Marcial, La Colorada, Campo Morado, La Preciosa, and Don David, all with grade*meter results over 10,000 gpt*m.

Epithermal systems dominate the list, with 34 out of 45 deposits in the list belonging to this category. Intermediate sulfidation epithermal deposits, the most common, include Los Ricos South (Jalisco), Pitarrilla (Durango), Plomosas-San Marcial (Sinaloa), La Colorada (Zacatecas), La Preciosa (Durango), Don David (Oaxaca), Columba (Chihuahua), Alamos Silver (Sonora), Zacualpan (Estado de México), El Tigre (Sonora), Cusi (Chihuahua), Los Gatos (Chihuahua), Tahuehueto, (Durango), Los Reyes (Sinaloa), Las Coloradas (Chihuahua), La Reyna (Nayarit) and Plomosas (Chihuahua). Intermediate sulfidation epithermal deposits with some evidence of low sulfidation mineralization comprise Cruz de Plata (Durango) and Panuco (Sinaloa), while Cristina (Chihuahua) and Gran Pilar (Sonora) are likely intermediate sulfidation epithermal mineralization distal to porphyry copper systems.

Low sulfidation epithermal deposits include Copalquin (Durango), San Dimas (Durango), La Colorada (Sonora), Santa Elena-Navidad (Sonora), Las Chispas (Sonora), Coneto (Durango), Claudia (Durango), Bolañitos (Guanajuato), Santa Elena-Luna (Sonora), Santa Elena-Santo Niño (Sonora), San Ignacio (Guanajuato) and El Cubo (Guanajuato). Palmarejo (Chihuahua), which displays the second-best intercept in second in the table, present mainly low sulfidation mineralization with local intermediate sulfidation style input.

Five of six skarn deposits, Media Luna, EPO, El Limón, ELG Underground and Media Luna West are part of the Guerrero Gold Belt, and only one, Bolívar is in Chihuahua. Cerro Las Minitas in Durango presents skarn and carbonate replacement deposit (CRD) mineralization. La Parrilla in Durango and Camino Rojo in Zacatecas present skarn, CRD and intermediate sulfidation epithermal mineralization styles.

Campo Morado in Guerrero is the only project present in the table that belongs to the volcanogenic massive sulfide (VMS) deposit classification.

Seventy percent of the silver intercepts of the table are sourced in four states: Durango (10), Chihuahua (8), Sonora (8) and Guerrero (6).

Mexico’s Best Gold Drilling Intercepts in 2025

During 2025 thirty-two companies presented gold results from drilling programs in forty-three deposits located in eleven states.

Heliostar Metals topped the list with an 83.2 m intercept at Ana Paula that averaged 17.30 gpt Au. Six of the first seven positions in the table below are from deposits located within the Guerrero Gold Belt. These are mostly skarn deposits and include Ana Paula (a complex deposit mineralization-wise), EPO, ELG Underground, El Limón Sur, Media Luna and Media Luna West. Other deposits with skarn affinities include Cerro Las Minitas and La Parrilla in Durango and Camino Rojo in Zacatecas, although also presenting carbonate replacement deposits (CRD) mineralization.

The most numerous deposit types in this table of gold drill intercepts are within the epithermal category, evenly split between the low and intermediate sulfidation divisions. Low sulfidation epithermal deposits include La Colorada (although some doubts remain on this one), Las Chispas, Santa Elena and Cecilia in Sonora; Palmarejo in Chihuahua (with minor local intermediate sulfidation input); Copalquin, Claudia, Coneto and San Dimas in Durango; San Ignacio, El Cubo, Bolañitos and Valenciana in Guanajuato; Panuco (also with intermediate sulfidation epithermal mineralization) and Los Reyes in Sinaloa and Los Ricos South (along with minor intermediate sulfidation mineralization) in Jalisco.

Intermediate sulfidation epithermal deposits in the list comprise Alamos Silver and El Tigre in Sonora; Columba, Cusi, Las Coloradas and Los Gatos in Chihuahua; Cruz de Plata (also with low sulfidation epithermal mineralization), Tahuehueto and La Preciosa in Durango; Plomosas-San Marcial in Sinaloa; La Colorada in Zacatecas; Zacualpan in Estado de México; Don David in Oaxaca and La Reyna in Nayarit. Other two deposits present intermediate sulfidation epithermal mineralization, but are probably distal parts porphyry copper systems: Gran Pilar in Sonora and Cristina in Chihuahua

Campo Morado in Guerrero is the only volcanogenic massive sulfide deposits drilled during 2025 with results published by the companies involved. Geographically, 53% of the deposits with gold results in drilling campaigns are in three states on the north of the country, Sonora, Chihuahua and Durango, while 16% are located in Guerrero.
